UPPER MARLBORO, Md. (WUSA9) -- Monday, former Metropolitan Police Department police officer Jamell Stallings was sentenced to more than a year in jail for stealing her brother's identity, says Prince George's County State's Attorney Angela Alsobrooks.

The 46-year-old Jamell Stallings was sentenced to 18 months for counterfeiting, identity fraud and theft.

According to Alsobrooks, Stallings stole the social security number of her brother, Ronald Greene. Greene agreed to go with Stallings to Navy Federal Credit Union and open an account, but without telling her borther, she added herself as the joint owner of the account, according to Alsobrooks. Stallings then took out a $5,000 loan using his name and SSN.

Stallings then generated a fraudulent W-2 that indicated Greene made $46,000 in 2006 at Brookstone Financial, even though the owner of that company said that Greene never worked for him (it was later discovered that Stallings' husband did work there). Stallings faxed the W-2 to Navy Federal from MPD District 5 in order to obtain the loan, according to Alsobrooks, and transferred $2,500 of that loan to her own account. She also spent the other $2,500 on other items.

According to Alsobrooks, Stallings also used her brother's name to take out a $13,000 car loan. She then forged the certified check that Navy Federal gave her to reflect that Greene gave her the funds. She then deposited it into her personal account. Alsobrooks says Stallings immediately took out another certified check for $13,000 from her account and used it to pay off her vehicle.

After her jail time, Stallings must complete 500 hours of community service, serve five years of supervised probation and enter a treatment program to deal with her gambling addiction, says Alsobrooks.
